Circuit for fingerprint security system

This is the circuit designed as a hobby project. Here, a fingerprint module has been automated to create an automated fingerprint security system. This circuit uses the Atmel IC 2051 i.e. AT89C2051 an 8-bit microcontroller IC.AT89C2051 is a low voltage, high performance CMOS 8-bit microcomputer with 2K bytes of flash programmable and erasable read-only memory (PEROM).It has operating range from 2.7V to 6V. AT89C2051 is also equipped within by a 128x8-bit internal RAM and two 16-bit counters. Also, general purpose switching and amplification transistors BC547 have been used in the circuit.
